Correct! True False True, but only when a low number of heme molecules are present False, but only when high WBCs are present. False, but only when high RBCs are present. Chapter 15, Inflammation section Question 6 (TCO 9) A human’s cellular ability to recognize and then defend against microbial invaders and their products is called _____. Correct! adaptive immunity prevention adaptive radiation molecular transference None of the above Chapter 16, Overview of Adaptive Immunity section Question 7 (TCO 9) The humoral immune response is attributed to the action of _____. neutrophils T lymphocytes Correct! B lymphocytes monocytes macrophages Chapter 16, The Tissues and Organs of the Lymphatic System section Question 8 (TCO 9) The most prevalent type of antibody in the blood is _____. IgD IgA IgM IgE Correct! IgG Chapter 16 Question 9 (TCO 9) Which of the following are functions of IgG? Antibody-dependent cellular toxicity Toxin neutralization Can help complement proteins Crossing the placenta to help protect the fetus Correct! All of the above Chapter 16, B Lymphocytes (B cells) and Antibodies section Question 10 (TCO 9) Cytotoxic T cells _____. are also known as natural killer lymphocytes Correct! are involved in killing cancer cells are the target cells of HIV All of the above None of the above Chapter 16, T Lymphocytes (T Cells) section Question 11 10 / 10 pts (TCO 9) List and describe the structure of each of the five classes of antibody molecules. Which one is produced first in the disease process? Which is the most prevalent? Answer: IgM comes first and then convert I gG is the most come and long lasting IgE release histamen IgD remains attached to b cells IgA body secrections Chapter 16, B Lymphocytes (B cells) and Antibodies section IgM is a pentamer of five subunits. IgG is a monomer, the most common and longest lasting. IgA is associated with secretions; secretory IgA is a dimer. Monomeric IgA is also found circulating in the bloodstream. IgE is a monomer and associated with allergic reactions and helminth infections. IgD is a monomer and often membrane bound. Its function is not known. IgM is produced first during the infection response. IgG is the most prevalent antibody. VERSION 2 1) Innate immunity and its preventative physiology can be seen in all but which of the choices below? Keratin of fingernails 2) The residual body is _____. the remains of a phagosome after digestion 3) The fluid called pus _____. contains WBCs and dead tissue 4) Membrane attack complexes (MAC) _____. are holes in the cell membranes of pathogens 5) A wandering macrophage may leave the bloodstream. True 6)A human’s cellular ability to recognize and then defend against microbial invaders and their products is called _____. adaptive immunity 7) The humoral immune response is attributed to the action of _____. B lymphocytes 8) The most prevalent type of antibody in the blood is _____. IgG 9) Which of the following are functions of IgG? All of the above 10) Memory B cells _____. do not secrete antibodies Question 11: A pregnant woman is sick with a rash, and her doctor is not sure whether she has fifth disease (caused by parvovirus B19) or rubella (caused by rubella virus). The physician requests antibody titer tests. The results are that antiparvovirus B19 antibodies are primarily IgM, and antirubella virus antibodies are all IgA and IgG. (a) Which disease does the pregnant woman currently have? How do you know? (b) Which disease has she had in the past? How do you know? Answer: (a) The pregnant woman currently has fifth disease. IgM is produced during the initial stages of an infection, so its presence indicates that the woman has a recent infection with fifth disease. (b) The pregnant woman has had rubella in the past, or been vaccinated against it. She has antibodies to the virus but no IgM indicating a recent infection.
